Plantar fasciitis (also known as plantar fasciopathy or jogger's heel) is a common painful disorder affecting the heel and underside of the foot. It is a disorder of the insertion site of ligament on the bone and is characterized by scarring, inflammation, or structural breakdown of the foot's plantar fascia.
Plantar Fasciitis is often caused by overuse injury of the plantar fascia, increases in exercise, weight, or age. The plantar fascia is the thick tissue on the bottom of the foot. It connects the heel bone to the toes and creates the arch of the foot. When this tissue becomes swollen or inflamed, it is called plantar fasciitis.
